The LG LA9650 has an IPS panel, while the Samsung F9000 uses a VA one, which means the latter has the upper hand when it comes to the black level, but the viewing angles are slightly inferior in comparison to the former one.

They both utilize local dimming, but the F9000 also features another technique called Micro Dimming Ultimate, which divides the screen into hundreds of zones and applies various enhancements to each zone individually (including brightness adjustment), thus it's able to further improve the contrast ratio, which is already excellent due to the VA panel, making it the better choice for a home cinema.

The LG model has a panel with native refresh rate of 240Hz, as opposed to the 120Hz one used by Samsung, meaning the LA9650 can deliver better results in terms of fast-motion performance, so it's more suited for sports viewing, for example. However, the difference between them is not night and day by any means, since additional video processing is used by both devices, including frame interpolation and backlight scanning for the purposes of removing motion blur and delivering smoother motion.

The LG comes with the passive 3D system, whereas its opponent has the active variant. The difference is that the former one relies upon polarization of alternate lines, so the vertical resolution is halved when in 3D mode. However, because the native resolution of the 4K is 3840 x 2160, the LA9650 is still able to provide Full HD 1080p in 3D, meaning the main disadvantage of the passive system has been (mostly) resolved by the Ultra High-Definition sets. Among the strengths of the passive design are the lack of any flicker and crosstalk the active systems might suffer from.

The Samsung 4K set has a quad core processor, while its counterpart from LG has only a dual core, so the former has an advantage over its opponent in terms of the responsiveness of the smart TV applications, as well as the faster web browsing and switching between content. The F9000 is also eligible for an update in the future via the Smart Evolution kit (sold separately, available in 2014), which once connected to the TV, it can deliver various improvements to your TV, such as a new software, more features and content, at faster speed.

The total audio power output is 70W on the F9000, while the LA9650 has only 34W.
